It is weatherbeaten from standing out on a boat in salt air for years and I think it is broken. When it spins up in the wind I do get a fluctuating *open circuit* voltage swinging around 10~20V on the meter, and the red LED goes steady on, and the brake feature certainly works. BUT- when I tee it up like this spinning open in the wind then jump it in to a somewhat low battery expecting it to put out some charging current, it doesn't. Well, it gets up to a maybe 1.5A on the amp probe, at the peak of a stiff say 15mph breeze, and that's it. (I'd expect it to be putting out more like 5~10A at that point.) Further the unit does not drop rpm when the low battery load is switched in like this as one would expect. But again the brake switch clamps the rpm down as it should. This leads me to believe maybe the stator is OK but the controller is fried. Would you agree? Also do you know if the older AIR models were also 3-phase, that I might adopt your nifty circuit above if I need to?Anonymoushttps://www.blogger.com/profile/11006407056383977615noreply@blogger.comtag:blogger.com,1999:blog-5721725055816349586.post-45204461513528631112012-04-30T16:26:34.584+02:002012-04-30T16:26:34.584+02:00Not really!

I have posted the circuit diagrams so It should be easy (assuming you have some electronics background) for you and others to build the controller and make improve on this design.Brian Ellulhttps://www.blogger.com/profile/00340397851775355849noreply@blogger.comtag:blogger.com,1999:blog-5721725055816349586.post-76308809503901954992012-04-30T01:02:59.036+02:002012-04-30T01:02:59.036+02:00Are you interested in selling this product if so h...Are you interested in selling this product if so how muchpobrianhttps://www.blogger.com/profile/01631257685693040622noreply@blogger.comtag:blogger.com,1999:blog-5721725055816349586.post-11401238191873582292012-03-26T08:53:06.555+02:002012-03-26T08:53:06.555+02:00The 7812 IC is only used to regulate the working v...The 7812 IC is only used to regulate the working voltage for the circuit (opamp, relays etc) and not to regulate the output from the turbine. The turbine 3-phase output is rectified and connected directly to the batteries and therefore there is no limiting on it's output.Brian Ellulhttps://www.blogger.com/profile/00340397851775355849noreply@blogger.comtag:blogger.com,1999:blog-5721725055816349586.post-20368480603974275522012-03-22T18:16:34.518+01:002012-03-22T18:16:34.518+01:00Great design!

That is small, considering the turbine should have a max power of 400W.<br /><br />I am on a design team working on a very similar project. We plan on using our own Buck/Boost converter for this voltage regulation instead of an IC.BriarPatch1337https://www.blogger.com/profile/17004482894389975503noreply@blogger.com
